Enter the finite geometric series from its given description, and then enter its sum.

Mama L [17]

Answer:

$a_n= 4(-5)^{(n-1)}$

-10416

Step-by-step explanation:

a = 4

r = -5

geometric series: $a_n=ar^{(n-1)} = 4(-5)^{(n-1)}$

Determine which term = -12500:

$a_n=-12500$

$4(-5)^{(n-1)}=-12500$

$(-5)^{(n-1)} = -3125$

$(5)^{(n-1)} = 3125$

$(n-1)ln(5) = ln(3125)$

$n-1 = ln(3125)/ln(5) = 5$

$n = 5 + 1 = 6$

$a_6=-12500$

Using geometric sum series formula: $S_n=\frac{a(1-r^n)}{1-r}$

Therefore, $S_6=\frac{4(1-(-5)^6)}{1-(-5)} =\frac{-62496}{6} =-10416$

Which expression is equivalent to 1.5 raised to the fifth power divided by 0.7 raised to the fourth power, all raised to the thi

zaharov [31]

The expression is equivalent to 1.5 raised to the fifth power divided by 0.7 raised to the fourth power, all raised to the third power is; Option A; 1.5 raised to the fifteenth power divided by 0.7 raised to the twelfth power

<h3>How to solve exponents?</h3>

We want to find the expression that is equivalent to 1.5 raised to the fifth power divided by 0.7 raised to the fourth power, all raised to the third power.

The sentence above can be expressed as;

((1.5⁵)/(0.7⁴))³

This can be broken down into;

[1.5^(5 * 3)]/(0.7^(4 * 3))

1.5¹⁵/0.7¹²

Looking at the options, the only correct one is;

Option A; 1.5 raised to the fifteenth power divided by 0.7 raised to the twelfth power
